I started my career as Microsoft Access Developer in 2000. Later I created VBA macro based applications in Access, Excel, Word and Outlook.
Then in the early 2000s I started to develop an intranet application in VB ASP.NET. In that time I got to know Microsoft SQL Server 7.0 and 2000.
I spent 8 years developing small applications and supporting them in .NET, VBA, VB and classic ASP. During that time I try to learn management and development of Microsoft SQL Server 2000 and 2005.
In 2008 I joined to a big company with hundred millions of clients as a Database Administrator of a very high performance and very high availability SQL Server Failover Cluster (5-10k Batch Requests/sec, 1-3k Transactions/sec, 10k connections/sec). It was a hudge jump for me and I had to grow up for the task. I made many mistakes but I learned much.
From 2012 I spent 2 years at CityGroup to learn culture of big multinational companies and practice English language with different dialects from all over the world.
With my new knowledges I continue my career at the biggest Swiss bank.
Finally I returned to Hungary and started an own business as freelancer focusing on Microsoft Data Platform (SQL Server and Azure).
In the last couple of years I helped many companies to fix their infrastructure, data logic and performance problems and trained around hundred participants on SQL Server related courses.
